1.4 SYSTEM DESCRIPTION

A. Anchorage Design Requirements 1. Safety anchor system design shall comply with current OSHA, ANSI, and local

regulations pertaining to window cleaning and fall protection in accordance with sections 1.1, 1.2, and 1.3.

2. Anchor system shall provide independent fall arrest anchorages in addition to suspension line anchorages for each descent location as required by OSHA and ANSI requirements. See diagram at end of this document.

3. System shall be designed to be compatible with current window cleaning industry standard equipment (examples: rope descent systems, boatswain chairs, swing stages, transportable suspension devises).

4. Structural design requirements of anchorages and tie-back a. Anchorage shall be capable of sustaining a minimum ultimate load of

5,000 lbs., in any direction the load may be applied, without fracture or failure.

b. Anchorage shall be capable of sustaining a minimum proof load of 2,500 lbs., in any direction the load may be applied, without permanent deformation or damage to anchorage.

c. Anchorages shall be designed with a minimum 1,250 lb. working load, in any direction the load may be applied.

e. Parapet or guardrails subject to direct loading by workers’ ropes, possibly cables, shall be designed to withstand such loading (typically 1,800 lbs) without damage to either the structure of the rigging component in contact with it.

5. Locate primary support and fall arrest anchors in conjunction with areas on façade of building needing to be serviced. Consideration shall be given to the type of suspension equipment that will be used at the building and conditions such as: workers’ reach, rigging methods, and roof edge conditions. Anchorages shall be unobstructed and located behind and in line with equipment or portion of building they are intended to service. Anchors shall not be located within 6 feet of the roof edge unless fall protection is provided to access those areas safely. (See illustrations on page 12: “Anchor Spacing Diagram” and “Outside Corner Layout Reference Diagram”).

Note: This specification does not address powered platform design or permanently installed roof mounted powered equipment. The IWCA I-14.1-2001 Window Cleaning Safety Standard states: “Rope descents shall not exceed 300 feet (91m) above grade unless the windows cannot be safely and practicably accessed by other means” (Section 5.7.12). Additionally, The ASME A120 Safety Requirements for Powered Platforms for Building Maintenance Standard should be consulted when designing such equipment.

B. Davit Design Requirements and Rigging Sleeve 1. Locate rigging sleeves and davits to accommodate suspended maintenance

during swing stage operations. Typical spacing of davits shall be column lines or



every 20 feet, on center, where possible. Typical spacing of rigging sleeves is 6 feet 8 inches, on center. Placement of supports should allow cables suspending powered equipment to hang either parallel and in plane or slightly angulated with the building façade as required by users. (See illustrations on page 11: “Suggested Rigging Sleeve Layout” and “Suggested Davit Layout”). Consideration should be given to operating other equipment that may be required for access.

2. Locate independent anchorages for personal fall protection when using rigging sleeves or davits in accordance with section 1.4(A) Anchorage Design Requirements (See illustrations on page 11: “Suggested Rigging Sleeve Layout” and “Suggested Davit Layout”).

3. Davits shall be capable of supporting an ultimate load of not less than 4 times the rated load. The rated load of the davit shall be based on the swing stage hoist and powered platform load capacity, which is frequently 1,000 lbs or more.

4. Manufacture shall provide engineer’s calculations and test report to verify that davit will support load requirements.

5. Outreach of portable davit boom shall not exceed 8 foot 6 six inches. 6. Rigging sleeves shall meet the loading requirements in Section 1.4(A) Anchorage

Design Requirements.

C. Horizontal fall restraint cable system 1. The Horizontal fall restraint cable system (HFRCS) shall allow up to two users to

traverse the length of the cable span, each using a single lanyard for traveling along the cable spans. Turns in the HFRCS will require a double lanyard. The HFRCS shall be designed for two users using an energy absorbing lanyard, which limits the force applied to the HFRCS to 900 lb. or less.

2. HFRCS shall spans shall not exceed 180 feet in length. 3. The horizontal line shall be constructed of 3/8” x 7 x 19 stainless steel, construction

grade, with breaking strength of not less than 12,000 lbs. 4. Horizontal lines shall be permanently attached to anchors with 2 non-corrosive

permanently swaged fittings swaged to manufacturer's specifications at each termination. Swages shall be verified not to loosen under load. Capacity of one swage shall exceed strength of wire rope.

5. Horizontal lines must be attached to anchorages designed to be capable of supporting a minimum 5,000 lb. However, the HFRCS cable and anchorages shall be independent of anchorages used for suspension in accordance with Section 1.4(A) Anchorage Design Requirements.
